It's a big, wide, webbed world out there, and for you smartphoners out there who want a lightning fast machine with unlimited data, you can finally have it all—if you know where to look. So to celebrate T-Mobile's release of its two speediest 4G smartphones ever, the Samsung Galaxy S II and the HTC Amaze 4G—both of which are capable of streaming TV and movies faster than home internet on their nationwide 4G network—and their best rate plan ever: unlimited data, talk & text for $49.99 each line per month, Lifehacker has teamed up with America's Largest 4G Network to bring you a little something called The Best Stuff Ever Series.

Below you'll find the films you should be watching, the music you could be downloading, the games you'll want to play and the twits you could be tweeting at—all on your 4G smartphone. But only if you have the best plan out there.

Watch

You know how it goes: There's nothing on TV but Mad Men reruns and a Nova special about the mating rituals of jungle cats. (Come to think of it, both shows are kind of about the same thing.) Cue the miracle that is Netflix's Watch Instantly section. With a constantly updating library, there is always something ready to watch within reach—especially if you're viewing from your phone! Here are some that you shouldn't miss.

Firefly:Admit it. You were a pretty big Buffy The Vampire Slayer fan a while back. And maybe still a little bit of a fan now. And you've been meaning to get into Firefly for how long now? From now until April 2012, you can keep the promise you made to yourself way too long ago by watching Joss Whedon's beloved space cowboy drama. But you should hurry because whether you admit it or not, you're going to want to rewatch every episode. Say goodbye to your social life.

Listen

Music is good for a lot of things: warding off subway crazies, providing a soundtrack to an otherwise boring jog, inspiring an impromptu dance party. So we're here to help you load up your droid with the best new releases so you can curate playlists so fresh for fall that your primary function on Earth will be to remind all of your friends and coworkers that they really need to upgrade their music.

The Roots, Undun:Late Night With Jimmy Fallon's backing band and alternative rap group, The Roots are back with a concept album designed to blow your mind. The whole album journeys through a reverse narrative arc, beginning with a postmortum Redford who is attempting to make sense of his former life and all of the things that led the his eventually coming "undun". Your cure for listening boredom is here at last. Click here to pre-order the full album.

Gruff Rhys, Atheist Xmas EP: If you're not really in a holiday mood this year, Super Furry Animals' Gruff Rhys has an album for you. The not even happy enough to be considered melancholy ep contains songs with titles like "Post Apocalypse Christmas" and "At The End Of The Line," making it the perfect record to remind you that it's okay to be sad on a happy holiday. Click here to pre-order the full album.

Amy Winehouse, Lioness: Hidden Treasures: Though it may seem like a no-brainer, the posthumous record from soul singer Amy Winehouse is every bit as good as you imagined it would be. Producers Mark Ronson and Salaam Remi sifted through past recordings of Winehouse's and added some reggae-influenced beats to create a record that's truly worthy of everything everyone loved about Winehouse. While it's unfortunate that she won't be around to make anymore records, we should consider ourselves lucky that we get one last glimpse of things she might've done.

Play

Productivity always takes priority, but even the most productive people have to take breaks sometimes. In fact, studies show most people need about a five-minute mental vacation for every hour of work. So here are some games for your phone that won't take up too much time, but are still incredibly fun.

Cigarette Fighter:Cigarette Fighter may sound like the name of a really cool superhero who somehow fights people with lit cigarettes, but it's actually a simple way to kill time while you're trying to quit smoking. Basically, you cut up a cigarette into little tiny pieces all while being careful not to slice up your lighter. You're thinking about doing it right now, aren't you? It's okay. That's why it's here—just don't inhale.
